IMPROVEMENT IN SELF-LUBRICATING BOLSTERS 0F SPINNING-MACHIhES.

Specification forming part of Letters Patent No. 43,430, dated July 5, 1864.

To all whom it may concern:

Be it known that I, WILLIAM` F. RirroN, of the city and county of Providence, in the State of Rhode Island, have invented a new and useful Improvement in Spindle-Bolsters; and I do hereby declare that the following specification, taken in connection with the drawings making a part ofthe same, is a full, clear, and exact description thereof.

` Figure l is a side elevation. Fig. 2 is a longitudinal section, through the middle of the rail and one of the bolsters. Fig. 3 is a top view. y

In the accompanying drawings, A represents a section of the rail of a spinningsframe, and B B the bolsters for the spindles;

The object of my invention is to .provide a bearing or bolster for the spindle which shallbe so constructed that the oil or other lubrieating-duid shall be constantlysupplied to the spindle as the same is required by means ot' a brous absorbent, and therebyeconomize the consumption of the oil by preventing unnecessary Waste, as well as dispense with much of the care and attention which otherwise would be necessary to keep lthe spindles properly lubricated.

The bolster B consists of a head, C, and a shank, D, the latter being of a less diameter than the former, but sufficienti y large to allow of a bearing, E, for thespindle to `turn in. The bolster is fitted into the rail as shown, and is secured thereon by the set-screw a, a cup or recess being made in the top of the rail, which is filled by the head C of the bolster when 1the same is in place. The shoulder,

which is formed by the dierence between-thedameters ofthe head C and the shank D, is seated upon a washer or gasket, b, at the bottom of the cup in the rail, designed to pack the joint and prevent the oil from leaking through and running to waste down the outer surface ot' the shank. In the head G ofthe bolster there are made two or more chambers, c c, for the accommodation of some fibrous material which is to be placed therein. These chambers are connected with the bearing in which the spindle turns by means ot' a duct, d, Fig. 3, and also with a groove or channel, F, inthe top of the rail. In the present instance the connection is shown in the form of a saw-cut through the diameter of the head,

`to secure by Letters Patent, is

1. The combination and arrangement of the chambers c c in the head of a spindle-bolster for holding an absorbent with the duct d through the axis of the head of the bolster, and the bearing E of the spindle, substantially as. described, for the purposes specied.

2. The combination of a channel, F, substantially as specified, in the rail, with a spindie-bolster constructed as herein described,

for the purposes mentioned.
